Siren electronics do not generate any radio frequency energy. The radio used for wireless communication does generate a radio frequency energy.
The length of time the transmitter is used is no longer than 2 seconds per status command. Radio transmitters are just 5 watts in either VHF 136-174 MHz or UHF 450-470 MHz. At these frequencies, transmit power and length of transmitting time, the siren
radios are not harmful.
